A donor film includes a base film, a light-to-heat conversion layer formed on the base film, and a transfer layer formed on the light-to-heat conversion layer, wherein the transfer layer is formed of at least two layers and its first layer adjacent to the base film is a polymeric material and its second layer above the polymeric material is a small molecular material. The donor film allows a polymeric material to be used as an upper layer in the organic layers constituting the full color organic EL display device when a lower layer of the organic layer is formed of a small molecular organic material. The donor film, a method for fabricating the donor film, and a full color organic EL display device fabricated using this donor film are provided. The EL display device according to the present invention has superior properties.
